Last month, we started hosting lessons on APIs to teach people all over the world how to harness the power of real web apps. Codecademy users have integrated videos into their websites, called/texted friends, shortened URLs, and much more. With Codecademy, we think we can bring the power of programming to everyone. That's why we're working with more companies you likely interact with every day in order to show you how programming can affect your workflow and daily life. Use Twitter? So do tens of millions of other people. Most of those people tweet from the Twitter app. With today's new courses, you can tweet from Codecademy or write your own cool scripts that tweet on certain triggers. That's just the beginning.

With these new API offerings, you'll be able to:

Control the cloud. With courses from Box and SkyDrive, you'll be able to store and access files from anywhere in the world.

Authenticate with other apps using OAuth. These days, countless web applications (including Twitter and Facebook) use OAuth to authenticate users. Let GitHub be your guide to the OAuth2 protocol.

Become a consummate consumer. Find the latest fashions with Gilt, the best restaurants from Ordr.in, and pay for it all with Dwolla.

And much more!

Whether you're looking to learn an API that will underlie your web app or you just want to pull in some data for your site, you'll find a ton of useful, customizable, and fun services in our latest batch of API lessons. Our partners have worked hard to bring you a host of new tools to integrate into your own projects—check them out!
